ROTARY BRUSH.

SPECIFICATION forming part. of Letters Patent. No. 336,8e2, dated February 23, 1886. Application filed January 28, 1855. Serial No. 154,l96. (No model.)

To all whom it may concern:

Be it known that I, RICHARD J. GURTIN, a citizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Rotary Brushes, of which the following isa specification.

My invention relates to rotary brushes such as are used by hair-dressers and it consistsin the hereinafterdescribed means of holding said brush when notin use out of the Way above the chair.

In the accompanying drawings, Figure 1 is an isometric view of my invention; Fig. 2, a vertical central section of the swinging supporting-tubes and an end elevation of a part of the brush,part of the frame,the catc'h,and part of the connecting-rod; Fig. 3, an enlarged side elevation ofthe male part of the ball-and-socket joint and the upper part of the outer tube; Fig. l, an enlarged front elevation of a part of the brush-frame, showing also a part of the brush shaft provided with a pinion, and a crank shaft provided with a gear engaging with said pinion; Fig. 5, a detached isometric View of the brush proper and its shaft.

The frame A consists of two U shaped straps, a a,of metal, placed at an angle to each other and connected at their open ends, and also connected by an arc-shaped strap, a which unites the closed ends of said U shaped straps a a. In holes a formed at the junction of the straps or a,turns the brush-shaft O. The brush proper,B,may be a cylindrical brush of ordinary construction; but I prefer to concave the surface of the brush from end to end, (see Fig. 5)tha-t is, to make the middle of the brush smaller than the ends thereof, so that the brush will better fit the head of the person whose hair is being brushed.

The brush B is operated by a crank or winch, D, applied to the end of its shaft 0; or, if desired, in order to attain greater speed, to the end of a shaft, 0, provided with a gear, 0, which takes into a pinion, c, secured to the brush-shaft C, said shaft 0 turning above the shaft 0 in bearings in the strap a,and retained in said bearings by the collar 0" and set-screw c,said collar 0 surrounding said shaft 0 within the frame and the end of said last-named shaft farthest from the crank not passing entirely through the side of the frame.

The top of the frame A is provided with a screw-threaded vertical stud, which enters a threaded bushing, e, in the lower end of the inner supporting-tube, E, and is prevented from turning by a set-screw,e, which is driven radially through the side of said tube E and bushing e and thrusts against said stud. The tube E slides freely in an outer tube,F,which is provided at upper end with a bushing,f,into which is screwed a stud, G, provided at its upper end with a segment of a sphere, g, (or sphere,)which is placed within and fits a socket or cavity, h, in the upper side of the socketplate H,said scgmentg and socket-plate forming a ball-and-socket joint, and the stud G projecting down through the opening h at the bottom of the socket l1. Thesocket-plate His provided with screw-holes, by means of which it is secured by screws to the ceiling above the chair in which the customer sits. The balland-socket joint allows the brush to be swung in any direction and the supporting tubes to be rotated about their axis.

\Vithin the tubes E F is a spiral spring, S, the ends of which are provided with hooks s s,which engage with the pins 6 fflwhich are driven through said tubes E F, respectively, So the pin 8 being near thelower end of the tube E and the pin f being near the upper end of the tube F. The spring S holds up the tube E, frame A, and brush B, but allows the brush to be pulled down as low as the head of a person sitting in the operating-chair by grasping and pulling down the handle J ,secured to the lower end of the strap a of the frame A. The handle J is grasped by the left l1and,and serves not only to draw down the brush proper, but 0 also to guide it over the head of the customer, while the brush is at the same time revolved by the right hand turning the crank. In order that the spring S may not be under constant tension when the brush is not in use, the 5 outer tube, F, is provided near its lower end with an annular shoulder or projection, f ,and a spring-catch,K,is supported vertically on the strap a, being fastened thereto by screws 70 7a, which pass through the foot 70 of the same into said strap and hooks over said shoulder when the brush is lifted high enough,said catch having a bevel, W, on top of the same, which allows it to slide upward over said shoulder,and a hook,k ,which, springing in over said shoulder, holds up the frame and brush. A short lever, L, is pivoted at one end on the frame, and is connected between its ends by a rod, N, to the catch K,above the foot of said catch, so that when the handle J is grasped by the left hand a finger of the left hand may be pressed on the free end of said lever L to draw the hook if off from the shoulder f The brush is thus held out of the way of the hair-dresser and his customers when not in use, but may be immediately moved into position for use.

The abovedescribed brush may be used with great advantage in places where power cannot readily be obtained, and can be operated and guided by any one.

I claim as my invention 1. The combination of the frame, the brush supported therein, the supporting-tubes sliding and turning one within the other, the outer one of said tubes being provided at its upper end with a ball-and-socket joint, the socket of which is adapted to be secured to the ceiling of a room, and at its lower end with an annular shoulder,an inner tube-sliding and turning within said outer tube and attached at its lower end to said frame, and a spring catch or hook supported upon said frame and adapted to engage with said shoulder, as and for the purpose specified.

2. The combination of the frame, the brush supported therein, the supporting-tubes sliding and turning one within the other, the outer one of said tubes being provided at its upper end with a ball-and-socketjoint, the socket of which is adapted to be secured to the ceiling of a room, and at its lower end with an annular shoulder, an inner tube sliding and turning within said outer tube and attached at its lower end to said'franie, and a spring catch or hook supported upon said frame and adapted to engage with said shoulder, a handle secured to said i'rame,a lever pivoted upon said frame, and a rod connecting said catch and lever, as and for the purpose specified.
